| hasDefinition | The limit, if it exists, of the quotient of the conditional probability that the instant of a failure of a non-repaired item falls within a given time interval (t, t + Dt) and the duration of this time interval, Dt, when Dt tends to zero, given that the item has not failed up to the beginning of the time interval. Notes. 1 An estimated value of the instantaneous failure rate can be obtained by dividing the ratio of the number of items which have failed during a given time interval to the number of non-failed items at the beginning of the time interval, by the duration of the time interval. 2 In English, the instantaneous failure rate is sometimes called "hazard function". |
